I was playing with a very similar chart! It is definitely an enticing pattern. Also check out a 14 day moving average, seems to be a good predictor of buy points.
I agree with the target of about 0.80 if it does recover from the current slide. Should know in next couple of days. I'm looking at a stop of 0.645, but hopefully sp won't break below 0.65 as there is a reasonable queue here.
